Resource segmentation to improve delivery performance

A flexible approach to segmenting a resource (e.g., a media resource, such as a media segment, or other resource, such as a resource normally fetched or pushed using general file transfer protocols like HTTP) into a plurality of fragments. By employing such an approach, the delay until the resource can be utilized at the client side is reduced. Certain embodiments are provided which apply the flexible segmentation approach to ISOBMFF media segments for video streaming, such as would be used with Live DASH streaming.

The systems and methods further providing for determining a subset of the plurality of individual data streams of the stitched data stream associated with a time period of the active data stream in the common audio timeline, selecting the alternate data stream from the subset of the plurality of individual data streams, and providing the alternate data stream to the computing device, wherein the display of the active data stream on the computing device transitions to the alternate data stream on the computing device in the common audio timeline.

Content-modification system with feature for detecting and responding to a content modification by a tuner device

In one aspect, a method is performed by a computing system that is in communication with a content-presentation device, where the content-presentation device is scheduled to perform, at a modification start-time, a content-modification operation that comprises modifying a modifiable content-segment that the content-presentation device is scheduled to receive. The method includes determining that the content-presentation device has detected, within a predefined time period after the modification start-time and during performance of the content-modification operation, a mismatch between reference fingerprint data representing the modifiable content-segment and query fingerprint data representing content received by the content-presentation device from a tuner device connected to the content-presentation device. The method also includes determining that the mismatch is due to the tuner device having modified the modifiable content-segment before the modification start-time and, in response to determining that the mismatch is due to the tuner device having modified the modifiable content-segment before the modification start-time, performing an action.

Secondary content insertion in 360-degree video

A secondary content such as an advertisement may be inserted based on users' interests in 360 degree video streaming. Users may have different interests and may watch different areas within a 360 degree video. The information about area(s) of 360 degree scenes that users watch the most may be used to select an ad(s) relevant to their interests. One or more secondary content viewports may be defined within a 360 degree video frame. Secondary content viewport parameter(s) may be tracked. For example, statistics of the user's head orientation for some time leading to tile presentation of the ad(s) may be collected. Secondary content may be determined based on the tracked secondary content viewport parameters).

A method for providing media content by a server, the media content comprising media components, each media component comprising initialization data and media data, the method being carried out by the server for a preselection of a plurality of media components, obtaining an indication of which initialization data of the plurality of media components should be used by a client to process media data of the media components of the preselection; and describing the preselection in a media presentation description, the description of the preselection comprising references to each media component of the plurality of media components and the obtained indication.

System and method for automatic synchronization of video with music, and gaming applications related thereto

A computer system including a server having a processor and a memory, the memory having a video database and a music database, the video database storing at least one video file having a plurality of video file markers, and the music database storing at least one music file having a plurality of music file markers, wherein the server receives and decodes encoded data from computer readable code, identifies and retrieves from the music database a music file based on the decoded data, synchronizes the retrieved music file with one of the video files by aligning the video file markers of the video file with the music file markers for the retrieved music file to produce a synchronized video-music file, and transmits the synchronized video-music file to a display, wherein the video file markers are generated for each video file and the music file markers are generated for each music file.

Methods and systems for predictive buffering of related content segments

The methods and systems described herein aid users by providing thorough and efficient content consumption. For example, the methods and systems buffer content segments related to a current portion of the content that the system is generating for display. The methods and systems determine a characteristic of the current portion of the content and related content segments based on the characteristic. Confidence scores are determined by the systems and methods for each of the related content segments, and one or more related content segments with higher confidence scores are buffered in memory. Accordingly, the methods and systems described herein provide a thorough viewing of content through related segments that are buffered in memory for quick access.

METHOD AND SYSTEM FOR OBTAINING VIEWING DATA AND PROVIDING CONTENT RECOMMENDATIONS AT A SET TOP BOX

A user device includes a viewer tracking module that tracks viewer events to form a viewer tracking log and a recommendation module that generates a timeslot viewing profile based on the viewer tracking log. The timeslot viewing profile includes television programs watched previously and a prioritized timeslot series profile determined by summing and prioritizing the count of a plurality of watched programs in a series. The recommendation module compares the timeslot viewing profile of available television programs during the timeslot, generates a first content recommendation list of available television programs, receives related content identifiers for related content that identify content that is available and is related to the television programs of the first content recommendation, and, based on the related content identifiers, generates a second content recommendation list including content that is available during the timeslot different from the first content recommendation list.

A computer-implemented method obtains a plurality of image files, each corresponding to an image in a video stream and builds a common file from a contiguous grouping of the plurality of image files. The video stream has a plurality of contiguous video segments, each having a first video frame, and the plurality of image files correspond to the plurality of first video frames of the plurality of video segments. The plurality of video segments are of approximately equal duration.

Network Video Streaming with Trick Play Based on Separate Trick Play Files
20180007451 · 2018-01-04 · ·

Network services encode multimedia content, such as video, into multiple adaptive bitrate streams of encoded video and a separate trick play stream of encoded video to support trick play features. The trick play stream is encoded at a lower encoding bitrate and frame rate than each of the adaptive bitrate streams. The adaptive bitrate streams and the trick play stream are stored in the network services. During normal content streaming and playback, a client device downloads a selected one of the adaptive bitrate streams from network serviced for playback at the client device. To implement a trick play feature, the client device downloads the trick play stream from the network services for trick play playback.
